I got to thinking about those toxic clouds pouring off the Chevron refinery blaze, and realized that I could be better prepped for the chemical part of NBC. (There's apparently no protection available from the toxic fumes expelled by the TV network of that name, though....)

Well, I remembered looking for masks on this forum a year or two ago, back when the subject of chlorine release from city water treatment plants came up. I did a forum search for posts I had made that included the word "chlorine," and found the post where I suggested this mask. It has a variety of filters for various hazards; I note that the 3M P100/Multi Gas Respirator Cartridge provides protection against organic vapors, particulate matter and chlorine, and is rated for "concentrations up to 10 times the Permissible Exposure Limit (PEL) with half facepieces or 50 times PEL with full facepieces."

ETA: This Web site has the same respirator mask for only $103.61 (compared to $163.95 for the originally-linked Web site).

American parachutists...devils in baggy pants...are less than 100 meters from my outpost line. I can't sleep at night; they pop up from nowhere and we never know when or how they will strike next. Seems like the black-hearted devils are everywhere....
